- Eight years ago, the average age of Rahul's family was 35 years. At that time, the total age of 6 members = 35 x 6 = 210 years.

- After 8 years, total age of those 6 members now = 210 + (8 x 6) = 258 years.

- A new baby was born 1 year ago, so the total age including the baby now = 258 + 1 = 259 years.

- Four years from now, the total age of all 7 members = 259 + (4 x 7) = 287 years.

- Average age of the family four years hence = 287 / 7 = 41 years.

Therefore, the correct option is:

- Option 1: 41 years
